Participants swallow up to a target dose of 12 capsules a day divided into three doses of 4 pills each dose for a total of 10 weeks. Participants will begin by taking one capsule, 3 times each day, increasing the dose by three capsules every two days up to a target dose of 12 capsules per day: 4 taken at 3 different intervals (or the equivalent in powder form). Some participants may need to increase the dose more slowly. They then enter an open label trial for a further 10 weeks with the same dose of Daily Essential Nutrients (DEN). Compliance will be monitored with diaries and pill counts. All participants will then be followed up naturalistically 6 months and 1 year post trial.

fMRI for a subset of 20 participants; First, high resolution anatomical MRI will be collected. Short echo (TE = 30 msec, TR = 2000 msec) 1H-MRS protocol will consist of two striatal voxels (right and left, 4cc, 192 averages) and two prefrontal voxels (4cc, 128 averages). All voxels will be analyzed using LCModel. Metabolites include glutamate and creatine. While the child is in the scanner, we will also conduct Diffusion Tensor Imaging (DTI): sensitive to tissue microstructure; Arterial Spin Labelling (ASL): provides non-invasive, whole-brain, quantitative cerebral perfusion measures and resting state functional connectivity: This is an fMRI acquisition with no task (actually the task is to stare at a cross). This allows inference of functional connectivity. We will also include at least 2 more clinically useful scans: a T2 and T2 FLAIR scan to help with a radiological screening.

Eligibility
Key inclusion criteria
1) between 7 and 12 years, 2) considered reliable and compliant with the protocol (including the ingestion of as many as 12 capsules/day with food), and 3) meet criteria for ADHD as assessed by the K-SADS, and the Conners Rating Scales (T score greater than 65 on both parent and teacher form for any of the ADHD DSM-IV subscales).
A subset (n=20) of children (males with Combined ADHD) will be asked to participate in an 1H-MRS pilot study in order to begin documenting the impact that nutrition has on the brains of ADHD children. Those participants must be compatible with the imaging scanner (i.e. no braces, no history of claustrophobia).
Minimum age
7 Years
Maximum age
12 Years
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
1) Neurological disorder involving brain or other central function (e.g., intellectual disability as assessed by the Wechsler Intelligence Scale for Children, autism spectrum disorder, epilepsy, MS, narcolepsy) or other major psychiatric condition requiring hospitalization (e.g. significant mood disorder or psychosis), 2) Any serious medical condition, 3) Any patient known to be allergic to the ingredients of the intervention, 4) Any known abnormality of mineral metabolism (e.g., Wilson’s disease, haemochromatosis), 5) Any other medication with primarily central nervous system activity, including stimulants. Participants must have been off of these medications for a minimum of four weeks prior to the trial.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Provided that an individual meets the inclusion criteria and does not meet exclusion criteria, the person is allocated the next available number. All pills (ie active ingredient or placebo) have been pre-packaged by the pharmacy who holds the randomization code. A sealed envelope is contained within each pill package only to be opened in an emergency (ie patient deteriorates significantly).
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The randomization will be done using software produced by www.randomization.com. Four lists will be generated and the pharmacy will randomly chose one list to use for the randomization.

Safety/efficacy
Statistical methods / analysis
Based on our initial pilot results (most effect sizes estimated at .8-1.2), using power = .8 to detect a large effect size (.8), with a two-tailed a=0.05, we estimate needing about 35 participants per group, a number we should be able to recruit over a two year period given our proven success in recruitment for the open-label ABAB trial. Assuming a 10-15% dropout and to allow for multiple analyses, we will aim for 50 per group.
The changes from baseline to the end of treatment will be compared between randomized groups using repeated-measures ANCOVA, with the baseline level as the covariate. Change measures assessed at the end of treatment with no baseline will be compared using one-way ANOVA. The differences between treatment groups in these measures will be summarized as the mean differences and 95% confidence intervals generated from the ANCOVA/ANOVA models. Categorical outcomes will be compared between groups using Chi-square tests and will be described using odds ratios and 95% confidence intervals. All analyses will be undertaken on an intention-to-treat (ITT) basis that includes all randomized participants analyzed according to the group to which they were randomized. For those participants not completing the 10 weeks, data from their final assessment will be used to evaluate the change scores. Secondary analyses will be undertaken on all outcomes using the per-protocol (completers) analysis set. All tests will be two tailed and any p values less than 0.05 will be considered statistically significant.
